Background: Asthma is associated with low-grade systemic inflammation, prothrombotic state, and premature atherosclerosis. Objective: To evaluate the relationships between asthma, inflammatory biomarkers, and parameters of endothelial dysfunction. Material and Methods: We analyzed flow-mediated dilatation (FMD) of the brachial artery and intima-media thickness (IMT) of the common carotid artery using ultrasound in 92 clinically stable adult asthmatics and 62 well-matched controls. We also measured blood levels of selected inflammatory and asthma-specific biomarkers, including interleukin (IL) 4, IL-5, IL-6, IL-10, IL-12 (p70), IL-17A, IL-23, and interferon γ, as well as a disintegrin and metalloproteinase domain–containing protein 33 (ADAM-33). In addition, we assessed endothelial damage using 2 laboratory biomarkers: circulating von Willebrand factor (vWF) and pentraxin-3. We analyzed relationships between the study variables and asthma severity, lung function abnormalities, airway remodeling indices on computed tomography, and transthoracic echocardiography parameters. Results: Asthmatics had higher IL-6, IL-10, and ADAM-33 levels. They were also characterized by 23% lower FMD% and 15% thicker IMT, as compared with controls (P

Aim: To evaluate treatment results in advanced/metastatic melanoma patients treated with anti-PD-1 immunotherapy in routine practice in oncology centers in Poland. Methods: Multicenter retrospective analysis included 499 patients with unresectable/metastatic (stage IIIC–IV) melanoma treated with anti-PD-1 in first-line therapy. Results: Estimated median overall survival (OS) and progression-free survival (PFS) were 19.9 and 7.9 months, respectively. Multivariate analysis confirmed that ECOG 0, no brain metastases, normal lactate dehydrogenase level and occurrence of immune-related adverse events (irAEs) were statistically significantly associated with improved OS and PFS. Any irAE occurred in 24% of patients. Grade 3 or Grade 4 irAEs occurred in 6% of patients. Conclusion: Analysis revealed a slightly worse OS in real-world treatment in comparison to clinical trials (KEYNOTE-006 and CheckMate 066). Polish population treatment results are similar to other studies of real-world data. PFS and ORR are similar in our research and clinical trials.

Introduction Patients with systemic sclerosis experience endothelial dysfunction and damage even in the absence of clinical manifestations. Aim To evaluate various methods for assessing the endothelial function for their applicability to clinical practice. Material and methods Forty-two patients (7 men and 35 women) with systemic sclerosis and 36 controls (11 men and 25 women) matched for age, sex, body mass index, smoking habit, and comorbidities were enrolled in the study. We assessed each participant for typical risk factors for cardiovascular diseases and measured serum levels of vascular cell adhesion molecule-1 (VCAM-1) and thrombomodulin together with flow-mediated dilatation (FMD) of the brachial artery and intima-media thickness (IMT) of the common carotid artery using ultrasonography. Results Patients with systemic sclerosis did not differ from controls in serum levels of VCAM-1 and thrombomodulin, however, the statistical analysis with adjustment for potential confounders revealed increased levels of thrombomodulin in the patients (p = 0.03). They also had a 45% lower relative increase of FMD (FMD%), and 13% higher IMT (p < 0.01, both, also after adjustment for potential confounders). In a simple regression model, lower FMD% was determined by age (β = –0.57, 95% confidence interval (CI): –0.72 to –0.43) and C-reactive protein levels (β = –0.38, 95% CI: –0.55 to –0.22). Thicker IMT was related to age (β = 0.64, 95% CI: 0.52–0.67), glomerular filtration rate (β = –0.34, 95% CI: –0.5 to –0.18), and blood thrombomodulin levels (β = 0.45, 95% CI: 0.13–0.76). Conclusions Patients with systemic sclerosis present with endothelial dysfunction which may be detected using ultrasonographic methods. The exact mechanism of observed abnormalities is unknown, but it is possibly related to the chronic inflammation and ischemia-reperfusion injury.

Introduction The treatment outcomes of patients with advanced/metastatic melanoma were poor before the use of new therapeutic options. Material and methods A retrospective analysis was conducted among 287 patients with unresectable stage III and stage IV melanoma treated at the Maria Sklodowska-Curie National Research Institute of Oncology Cracow Branch, from 2013 to 2019. All enrolled patients were treated with immunotherapy (IT; consisting of pembrolizumab/nivolumab, or ipilimumab) or target therapy (TT; consisting of vemurafenib ±cobimetinib or dabrafenib ±trametinib) in at least one treatment line. Results mutation was detected in 152 (55%) patients. In general, the majority of patients (92%) were in very good or good condition (Eastern Cooperative Oncology Group [ECOG] 0 or 1). Brain metastasis was detected in 64 (22%) patients. Median OS and PFS in the experimental group from the beginning of the first-line treatment were 14.9 and 6.7 months, respectively. Across the study population, as a first-line treatment patients received IT, TT as well as CHT, and the median OS was 19.2, 12.6 and 15.9 months, respectively. Multivariate analysis confirmed that normal LDH levels, no brain metastases, ECOG 0, and objective response to the treatment were strong predictors of longer OS. For PFS, absence of brain metastases, ECOG 0, and treatment response were found to be predictive factors on multivariate analysis. Conclusions The administration of new therapies for the treatment of patients with advanced/disseminated melanoma significantly prolonged survival in this group of patients. Nevertheless, further studies should be conducted to assess the effectiveness of various sequences of treatment.

Background Atrial fibrillation (AF) is a frequent comorbidity in malignant patients. Anticancer therapies complicate anticoagulant strategy. We evaluated the safety and efficacy of long-term use of direct oral anticoagulants (DOACs) in breast cancer women. Methods In a prospective cohort study we enrolled 48 consecutive radically treated breast cancer women with AF (median age 63 [interquartile range 56–69] years, CHA2DS2–VASc 2 [2,3]) score) and adjuvant hormonal therapy. Thromboembolic complications (stroke, transient ischemic attack [TIA], venous thromboembolism [VTE]) and bleeding events (major and clinically relevant non-major bleeding [CRNMB]) were recorded in follow-up. Results During a median follow-up of 40 (interquartile range 28–50.5) months 13 (27%) patients received apixaban, 22 (46%) rivaroxaban, and 13 (27%) dabigatran. One stroke (2.3%/year) and two CRNMBs (4.6%/year) were observed on apixaban. One TIA (1.3%/year), three major bleedings and two CRNMBs (6.7%/year, combined) were reported on rivaroxaban. Three VTE were documented in dabigatran treated individuals (7.8%/year), without any bleeding or cerebrovascular events. Women with thromboembolic events had higher body mass index (32 [29–33]) vs. 26 [24–29]) kg/m2, p = 0.02) and CHA2DS2–VASc score (3 [3]) vs. 2 [1–3]), p = 0.02). Most thromboembolic complications (n = 4, 80%) and all three major bleedings were observed in tamoxifen users, while three of four CRNMBs occurred on aromatase inhibitors. Mortality rates were low (apixaban, n = 1 [2.3%/year], rivaroxaban, n = 3 [5.22%/ year], and dabigatran, n = 2 [4%/ year]). No death was related to bleeding. Conclusions This study suggests that DOACs are an effective and safe therapeutic option in breast cancer patients with AF during adjuvant hormonal therapy.

Background Granulomatosis with polyangiitis (GPA) is a rare granulomatous vasculitis affecting small- and medium-sized blood vessels. In optimally treated patients with long-standing disease, the common cause of death is atherosclerosis even in the absence of typical risk factors. Objective To evaluate endothelial dysfunction in GPA patients. Methods 44 patients (21 men and 23 women) diagnosed with GPA and 53 controls matched for age, sex, BMI and typical risk factors for cardiovascular diseases (22 men and 31 women) were enrolled in the study. We measured each participant’s serum levels of vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), and thrombomodulin. We also studied flow-mediated dilatation (FMD) of the brachial artery, intima-media thickness (IMT) of the common carotid artery and aortic stiffness using echocardiography. Results Patients with GPA showed a 15.9% increase in serum levels of VCAM-1 (p = 0.01), 66% of IL-6 (p

Acquired haemophilia A (AHA) is a rare autoimmune disease caused by antibodies directed against clotting factor VIII. About half of cases are idiopathic, but AHA may also be secondary to autoimmune, dermatologic, or oncologic diseases. In approximately 10% of non-idiopathic cases, the disease occurs after or with the diagnosis of cancer as an extremely rare paraneoplastic syndrome. We describe the case of a 73-year-old male patient diagnosed with AHA and successfully treated with recombinant human activated factor VIIa and immunosuppression. Two and a half years later, however, the disease relapsed and a routine ultrasound revealed a liver tumour that was then diagnosed as hepatocellular carcinoma. We present this case to increase awareness that this life-threatening condition may develop years prior to the diagnosis of cancer.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of vasculitis associated with asthma and eosinophilia. Endothelial dysfunction has been well documented in other types of vasculitis but not in EGPA. Thirty patients (10 men and 20 women) diagnosed with EGPA and remaining in a remission, and 58 controls (24 men and 34 women) matched for age, sex, and body mass index, were enrolled in the study. We assessed each participants for typical risk factors of cardiovascular diseases and measured serum levels of vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), and thrombomodulin. We also measured flow-mediated dilatation (FMD) of the brachial artery and intima-media thickness (IMT) of the common carotid artery using ultrasonography. Patients with EGPA had 20% higher serum level of VCAM-1 (p
